经过广泛的试验研究,煤矸石材料的各项指标符合高速公路路基填料的质量要求,正在作为一种新型的路基填料进行大范围的推广,但是由于煤矸石性质介于土和石之间,施工方法和质量检测在路基规范中没有具体明确。文章根据实践经验,介绍了煤矸石作为高速公路路基填料时的施工质量控制方法和检测方法。 After a wide range of experimental studies, the coal gangue material indicators in line with the quality requirements of highway subgrade filler, is being used as a new type of subgrade filler for a wide range of promotion, but because of the nature of gangue between soil and stone, construction Methods and quality testing are not specifically defined in subgrade codes. Based on the practical experience, the article introduces the construction quality control method and testing method of coal gangue as the subgrade filling of expressway.
